ABAP – S/4 – If Line_exists

Here’s another new one I discovered.  How often you do write a few lines of code to check if something exists?  For example, a common thing I do is look for an entry in a table?  If it’s there, I need to do something, if not, I move on. For example:

read table Lt_test transporting no lines with key key1 = val1 key2 = val2.

if sy-subrc = 0.

…

else.

…

endif.

Well, in S/4, that has been condensed.

if line_exists( lt_test[key1 = val1 key2 = val2]).

…

else.

…

endif.

you get to skip the read statement.  Now, if you need the contents, this might not help as much, since you would need to extract that line anyway, but if you are purely looking for the existence, then it’s a lot cleaner.
